摘要:The invention relates to commercially viable process for the synthesis of key intermediates for the preparation of statins, in particular Rosuvastatin and Pitavastatin or respective pharmaceutically acceptable salts thereof. A new simple and short synthetic route for key intermediates is presented which benefits from the use of cheap and readily available starting materials, by which the conventionally most frequently used DIBAL-H as reducing agent can be avoided.

摘要:The present invention describes the improved process for the preparation of montelukast acid (VII) and its pharmaceutically acceptable salts and esters using a novel synthesis step. The process is cost effective, environment friendly, and easily scale up to commercial level and leads to products having high chemical and optical purity. Moreover, the present invention provides a novel crystalline intermediate (IV) that is useful in this process and a method for its production. In a further aspect, the process of the present invention includes a step of removing ketone by-products be derivatization.

摘要:The present invention relates to a cephem compound of formula (III) shown in the description. The compound is useful as an intermediate for the synthesis of beta -lactam antibiotics of new class and also to a process for producing the same. The cephem compound (III) is produced by reacting a cephem compound of formula (I) with a nitrogen-containing compound of formula (II) under acid-capturing conditions. The process can be performed easily under mild conditions.
